It's technically possible, but probably not practically.  The imx28 RM
does not mention i2c clock at all, and I was told by designer that i2c
always runs at the same frequency as apbx, which sources from ref_xtal
(always 24 MHz).  Though there is a divider for apbx clock, it seems
every single running system sets the divider as 1 all the time.  That
said, what I have seen is the i2c clock is always 24 MHz.
